The RCM "Street Spec" conrod has been introduced to compliment our existing range, fitting between OE and the RCM / Arrow H section rods, rated up to 400Bhp. Not recommended for use with sequential or flat shift configurations. Manufactured from 4340 forgings to our exacting standards, each set of rods is weight matched to +/- 1.5 grams. Once the big and small ends have been checked, 3/8" ARP 2000 fasteners are fitted, before quality quality seal is applied with the RCM Logo.
